I have been on the B bodies only sight for years and have pictures posted there. I have read multiple times for the best advice for a small block is here so I joined. Thanks for the advice on the gearing. So what type of TC would you go with or what stall speed? Thanks again

That would be best suggested by the convertor manufacturer.
Call them up and tell them what you have and what you want out of it.
Be specific and as accurate as you can on the answers to the questions they ask.
